I dive in the Galapagos and here, every dive is a shark dive. I stopped thinking of white tipped reef sharks as sharks long ago. We head to Gordon Rocks for the hammerheads. Every dive you hope to see hammerheads and Galapagos sharks. While silkys also abound and can be more curious, I'm yet to see those. Good advice about the hunting and murk. We don't always have the best visibility here, but I can say that I am not aware of any divers attacked by sharks in spite of how many dive with them each and every day. The only shark attacks I've ever heard about in the Galapagos happened to surfers, snorkelers and one guy swimming around cleaning the bottom of a boat.
Perception is an interesting thing because it's not the sharks that scare me, but the macho sea lions. I'm still amazed every time I see a diver on a video reaching out to touch a sea lion while diving. No one would walk down a neighborhood street reaching out to touch the big German Shepherds and yet, that's is the size of a sea lion's teeth. Anyway, the bull males scare me a lot. They can and do bite if guarding their territory and that's all they do for weeks each year is guard their territory and fight for it. I've had hammerheads and macho sea lions at close range underwater, but only the sea lion is scary. I'm more afraid of scaring away the hammerheads with my bubbles (which does scare them away). Sea lions translate bubbles as a sign of agression.
And yet, sea lions are always perceived of as cute, cuddly and harmless. Orcas, too, post free-Willy. I have never liked being on the surface...always did intuitively feel like prey up there. But down under, I'm a part of the environment and to sea life, essentially an unknown part given man's relative short period of time under the sea. So nothing is ingrained in terms of me being an enemy, a meal or anything. I get to determine that by the manner in which I dive. The Galapagos wildlife above land shows you that if you do not threaten, the animals are not afraid. I think that is true underneath the sea here as well as on land. God knows the sheer abundance here means nothing goes hungry.
Night dives are illegal here, but even when they weren't, I never heard of anyone being attacked by the many, many sharks that are always in the water here. Me? I'm not snorkeling around sunset myself. PS...first time I ever went snorkeling in the Galapagos, I swam into a canal with somewhere between 24-30 white-tipped reef sharks, had two swimming beside me on the way out as I tried to keep up with an eagle ray. I truly believe so much is about perception and the rest about common sense.
